Due to the new system architecture of arcgis for server 10.1 I am first writing here to ask if anyone has successfully migrated from AGS 10.0 to 10.1 and what problems were encountered. I am currently serving data on Windows 2008 R2 with ArcGIS Server 10.0. I have about 20 map-client applications using aounrd 50 AGS services and no Fail-Save system. Around 400 People use the clients in my organisation.
As I am relatively new to ArcGIS server and the windows server environment (I was previously in an organisation which used Linux Ubuntu server,Apache, tomcat6, geoserver with PostgreSQL) I am quite worried about things not going to plan!
If anyone can offer some good advice, I would be very very grateful,
Yours,
Robert
